Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMDT2222V-TP is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor configuration: 2 NPN (Dual)
• Maximum collector current: 600mA
• Maximum collector-emitter breakdown voltage: 40V
• DC current gain (hFE): minimum 100 @ 150mA, 10V
• Transition frequency: 300MHz or greater
• Vce saturation: 1V @ 50mA, 500mA

Mechanical Compatibility Criteria:

• Surface mount technology
• Package compatibility: SOT-563, SOT-363, SC-88, or SC-70-6 (all equivalent 6-pin surface mount packages)
• Moisture sensitivity level: 1 (Unlimited)

Compliance Requirements:

• RoHS3 compliant
• REACH unaffected status

Substitute parts are grouped into two categories: Direct Equivalents (identical electrical specifications and primary package) and Functional Equivalents (identical electrical specifications with alternative package options).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Pin-Compatible Replacement):

MMDT2222V-7 manufactured by Diodes Incorporated is the primary direct equivalent. This part maintains identical electrical specifications and SOT-563 package compatibility with the obsolete MMDT2222V-TP. The part is active in production with substantial inventory availability (106,839 pieces), ensuring supply continuity. Full RoHS3 compliance and MSL-1 rating match the original specification.

Functional Equivalents (Alternative Package Options):

The following parts provide electrical equivalence with alternative surface mount packages (SOT-363, SC-88, SC-70-6) suitable for designs permitting package substitution:

• CMKT2222A TR PBFREE (Central Semiconductor Corp): Offers increased power dissipation (350mW) and extended lower operating temperature (-65°C). Package change from SOT-563 to SOT-363 requires PCB layout modification.

• MBT2222ADW1T1G (onsemi): Maintains 150mW power rating with SC-88/SC70-6/SOT-363 package options. Active product status with high inventory (65,100 pieces).

• MMDT2222A-7-F (Diodes Incorporated): Provides increased power dissipation (200mW) in SOT-363 package. Active status with 17,680 pieces available.

• NSVBT2222ADW1T1G (onsemi): Matches original electrical specifications with SC-88/SC70-6/SOT-363 package flexibility. Active product with 8,911 pieces in stock.

Not Recommended for Direct Substitution:

MMDT4401-7-F exhibits reduced transition frequency (250MHz versus 300MHz) and altered Vce saturation characteristics (750mV @ 50mA, 500mA versus 1V @ 50mA, 500mA). These deviations may impact circuit performance in frequency-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can MMDT2222V-7 be used as a direct replacement for MMDT2222V-TP?

A: Yes. MMDT2222V-7 is electrically and mechanically equivalent. Both parts feature identical collector current (600mA), breakdown voltage (40V), saturation characteristics, current gain, transition frequency (300MHz), and SOT-563 package. The primary difference is product status: MMDT2222V-TP is obsolete while MMDT2222V-7 is active in production.

Q: What is the difference between SOT-563 and SOT-363 packages?

A: SOT-563 and SOT-363 are both 6-pin surface mount packages with identical electrical pin configurations but different physical dimensions and land patterns. PCB layout and footprint modifications are required when substituting between these packages. SC-88 and SC-70-6 are alternative designations for the same package family.

Q: Can I use CMKT2222A TR PBFREE in place of MMDT2222V-TP?

A: Electrical substitution is valid. CMKT2222A TR PBFREE meets all electrical requirements with identical collector current, breakdown voltage, and current gain. However, the package changes from SOT-563 to SOT-363, requiring PCB redesign. The part offers higher power dissipation (350mW) and lower minimum operating temperature (-65°C), which may provide design margin in thermal or temperature-sensitive applications.

Q: Why is MMDT4401-7-F listed as a substitute if it has different specifications?

A: MMDT4401-7-F is included because it was referenced in the original MMDT2222V-TP substitute list. However, the reduced transition frequency (250MHz) and altered saturation voltage (750mV) represent functional deviations. This part is suitable only for applications where these parameter changes do not impact circuit performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the original MMDT2222V-TP specification. All parts also maintain MSL-1 (Unlimited) moisture sensitivity rating.

Q: What inventory considerations should guide part selection?

A: MMDT2222V-7 offers the highest inventory availability (106,839 pieces), providing supply security for volume production. MBT2222ADW1T1G (65,100 pieces) and MMDT2222A-7-F (17,680 pieces) provide secondary sourcing options. NSVBT2222ADW1T1G (8,911 pieces) and CMKT2222A TR PBFREE (6,461 pieces) offer tertiary alternatives with lower stock levels.

Q: Can package substitution affect circuit performance?

A: Package changes may introduce minor variations in parasitic inductance and capacitance due to different lead frame geometries. For high-frequency applications operating near the 300MHz transition frequency specification, package-induced performance variations should be evaluated through circuit simulation or prototype testing. For general-purpose switching applications, package substitution typically presents no functional impact.
